Home Forums Hunting & Shooting Handguns Handgun for hunting whitetail

I’m looking to get another handgun to hunt whitetail I been hunting with a tc but would like something that has follow up shots if needed.
I am looking for suggestions due to being a novice handgun hunter.
I was looking at a sw frame in 460 due to being able to shoot 454 and 45long colt in a 5 inch barrel.
Should I look at a longer barrel?
Open to suggestions on different guns and calibers
